Working principle of XCL101A281ER-G

The operating principle of XCL101A281ER-G is based on the Buck Converter topology. It works by controlling the voltage from the input power source and stepping it down to the required output voltage level. It performs this task through the use of a transformer, the core of which is formed by a ferrite material, and a set of electronic switching elements.

When the voltage is higher at the input source than the required output voltage, the converter operates as a "Boost" converter, where the higher input voltage is reduced to the desired level. When the input voltage is lower than the required output voltage, the converter operates as a "Buck" converter, where the lower input voltage is stepped up to the desired output voltage.

The converter works by switching the transistor elements from "on" to "off" according to a specific clock frequency. This is known as Pulse Width Modulation (PWM) and it is used to modify the power level to the transformer, thus resulting in the desired output voltage. The PWM frequency is the key factor that determines the converter\'s efficiency.

The XCL101A281ER-G implements a dual-channel synchronous buck converter, providing up to 10A output current. With its high efficiency design, it provides steady and reliable output voltages, even in conditions with wide temperature range.
